The MULTICRETE II underdrain is a monolithic cast in place underdrain with open plenum design. It can be designed for media retaining or support gravel applications. Special nozzles allow for combined air/water backwash or water only backwash.

The accessible MULTICRETE II underdrain allows interior inspection after installation. The open plenum design provides for uniform distribution at high rates of air and water during backwash. It readily combines with the unique MULTIWASH baffle to provide unlimited air-water backwashing. MULTICRETE II is NSF Standard 61 approved.
